Ditched the junk pacesetter y-pipe for this!!!
Still haven't seen proof that the 1 7/8 is worthwhile overall for <500 RWHP -- sure seems you would suffer on the low end.
When I say proof, I really think the test would have to be with say ARH Headers & Y and the rest of the car unchanged except for say an SLP FlowPac and this same car dyno'd on both 1 3/4 & 1 7/8.

Yeah, but even the merges on a lot of Y pipes look like garbage. You'd think they could at least put something nice on there.
I had a fab shop that does **** like that do one for my car. Mine looks good and is a lil larger,but your's looks even better.. Throw another pic when it's all done. You are running a catback too,right??
Looks like the y merge that lsxtremeperformance used to make. That's the one I had picked out if I didn't go true duals. I checked their site last night, and they're shut down 
Just sucks b/c they actually made a really good Y pipe.

Nice looking y-pipe, keep us posted if it picks up the power you were talking about!
I just wanted to add a pic of the flowmaster and magnaflow mufflers I'm running......
I'm finally going to the dyno Monday and the changes are..this exhaust, fast 102vs fast 92, and +4cc pistons...so compression is up .4 from 11.0 to 11.4
Last dyno run was 451 rwhp 380rwtq through an unlocked vig 3600 converter 4l60e 3.73 12 bolt

So far no rasp, it sounds really deep...almost like an old school big block.
The setup is dumped right at the axle...from inside the car its not to loud at all, I can still listen to my radio and cruise at 70 no problem. But from the outside it juist seems like there is a big cubed motor under the hood pounding the ground.
There was more rasp with the factory catback setup.

That looks IDENTICAL to the inside of my Hooker MaxFlow muffler.
All the power and half the sound....works great for roadtrips and when I have to get her inspected...otherwise too damn quiet.

Video with sound clip on the dyno to come Monday...in the upper rpms you can still tell its LS!!! My car revs and makes power to about 6,800, and my rev limiter is set to 7,200, so we will get a good sounds range throughout the rpms. I should also have a print out of my old dyno and this new one...
If you need/want a shorter Y-merger consider a one from Vibrant Performance, they're a work of art!
